office365users.myprofile() suddenly started returning 403 errors

I've been using Office365Users.UserProfile(User().Email) to populate a profile form and it's been working successfully for the last two weeks. But today (when I shared it out for UAT, of course) it has started to return 403 errors every time.

I tried MyProfile instead, and got the exact same error.

The service returned an error: Office365Users!UserProfile: {"status":403,"message":"Insufficient privileges to complete the operation.","source":"127.0.0.1"}

The service returned an error: Office365Users!MyProfile: {"status":403,"message":"Insufficient privileges to complete the operation.","source":"127.0.0.1"}

I'm encountering this issue both in browser, web editor preview mode and on the phone app (iOS)

Engineers have resolved the issue, but existing connections will continue to experience errors for up to another hour. New Office 365 Users connections will work correctly. Last updated at: 4/15/2017 2:00 PM PST
